Everything you need to know about Multi Mill

What is Multi Mill?

 Multi Mill is a self-contained portable device that can granulate, pulverize, blend, shred, and chop a wide variety of wet and dry materials at high speeds without the need for special attachments.

This machine uses the concept of variable force swing hammer blades with both knife and impact edges rotating with a carefully chosen screen to regulate size reduction, as opposed to the four traditional principles of size reduction, i.e. grinding, compression, impact, and shearing, which often do not achieve regulated size reduction.

In a vertical rotor machine, the material flow path is simplified. Stuff entering the chamber moves to the periphery and passes tangentially and radially through the screen during comminution, preventing choking and temperature increase. The capacity of the multi mill is 1HP and 3HP.

Components of Multi Mill

Hopper inlet: The hopper is where goods are fed into the mill.

Milling Chamber: The milling chamber has a screen to minimize particle size, as well as twelve milling and cutting edge blades, as well as two scraper blades.

Discharge Point: The milled items are collected using these components.

Electrical chamber and mechanical chamber: All mechanical components such as gears, motors, and moving belts, as well as electrical components such as wiring, switches, and MCVs, are installed in this segment.

Application of Multi Mill 

Multi mills can be used in a variety of applications, including wet and dry granulation, pulverization, and more. Pharmaceuticals, cosmetics, dyes, paints, food goods, herbs, detergents, insecticides, plastics & resins, fertilizers, and other industries benefit from the multi-mill unit. With ISO certification and international guidelines, we are the best multi-mill producer, exporter, and supplier.

Working principle of multi mill 

The concept involves rotating blades with both knife and sharp edges with a validated screen size to minimize particle size in a regulated manner using a variable force. The mechanism includes a pulverization process (pulverization is the grinding and crushing of materials into small particles) in which a knife is used to cut large particles into small particles, which are formed from granules during the drying process. 

Speed range of multi mill 

The multi mill can be run at a variety of speeds ranging from 720 to 2880 RPM (also depends on manufacture).

Features of Multi Mill 

  • All parts are made of the stainless steel grade 304/316.
  • All pieces, especially those that come into contact with the product, are simple to disassemble and clean.
  • Blades and scrapers are made of tough materials and rough chrome-plated.
  • Can be continuously run for a long time.
  • For high performance, a cylindrical drum is used.

Advantages and Disadvantages of Multi Mill 


  • Can be used for wet-milled materials.
  • Operational activity is easy.
  • There are also options for variable rpm.
  • It’s easy to take apart and clean.
  • Installation took up less room.


  • It adds to the noise.
  • The risk of an accident increases as the speed varies regularly.
